ALBERT PARKER, OF HARVEY, ILLINOIS.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 600,927, dated March22, 1898.

Application filed January 22, 1897. Serial No. 620,175. (No model.)

To all whom it may concern:

Be it known that I, ALBERT PARKER, a citizen of the United States,residing at Harvey, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Harvesters; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to that class of harvesters which are commonlyknown as headers and which are adapted to remove the heads of the grainfrom the standing stems. Machines of this kind are ordinarily mountedupon two main drive-wheels and are driven from behind, a frame extendingforwardly and carrying a grain-platform and the sicklebar, both of whichextend across the entire front of the machine. It is necessary that thisforwardly-projecting frame and its accessories be vertically adjustable,and difficulty has arisen in so constructing machines of this characterthat the adjustment of this frame shall not unduly strain the main frameof the machine and shall not disturb the relation of the workingmechanism. I have solved these problems by pivoting both the forwardlyprojecting frame and the rear frame upon the main drive axle or shaft ofthe machine in the manner hereinafter fully described, so that theflexure is upon the axle as an axis.

In illustrating my invention I have not deemed it best to show anythingmore than a skeleton frame of the machine, and it will be understoodthat in practice suitable cutting and delivering mechanisms are mountedupon the frame, together with proper gearing to operate them from themain drive-shaft, and also that suitable levers are employed for tiltingthe forwardly-projecting frame.

Figure 1 of the drawings is a plan view of the frame of a header,showing my improved construction. Fig. 2 is a side elevation of thesame. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4 is adetail section on the line 4. 4 of Fig. 3. Fig. 5 is a detail section onthe line 5 5 of Fig. 1. Fig. 6 is a detail elevation of the same partsshown in Fig 5, but viewed from a standpoint ninety degrees removed fromthe point of view of Fig. 5. Fig. 7 is a detail section on the line 7 7of Fig. 1. Fig. 8 is a detail elevation viewed in the direction of thearrow 8, and Fig. 9 is a detail viewed from the line 9 9 of Fig. 8.

A pair of main drive-wheels are shown at A and are mounted upon adriving axle or shaft B. The pole or tongue O,by means of which power isapplied, bears upon the axle B and is stayed by suitable brace-rods c 0,leading to the axle and pivotally connected therewith by means ofjournal-blocks c c. The U-frame D has its ends journaled upon the endsof the axle B and extends backward] y around the drive-wheels, crossingabove the pole O, to which it is rigidly secured by means of a suitableblock d, suitable castings E E being employed to connect it also withthe brace-rods c c.

The grain-platform F is mounted at the front of the machine and issupported by a pair of line-levers G Gr,which are rigidly fixed toa-tube, preferably a piece of gas-pipe H, sleeved upon the centralportion of the axle B and being of such length that its ends abutagainst the journal-blocks c c. The platform F is stayed by brace-rods gg, pivotally mounted upon the axle B between the journals of the U-frameD and the drive wheels A A.

The line-levers G G are secured to the tube H by means of U -bolts K, tothe ends of which are applied clips is, held by nuts L L, applied to theends of the U-b0lts. The line-levers are preferably flat rods, theirgreatest dimension in cross-section being vertical, and are applied tothe under side of the tube 1H and are recessed, so that it may be letinto them a short distance. In order to strengthen the connectionbetweenthe. lever and tube, the former is preferably provided with anupstanding lug h at the bottom of its tube-receiving recess, and thetube is suitably apertured to receive this lug.

I prefer to have the tube I-I bear upon the axle B only at the ends ofthe former, and to this end the bore of the tube exceeds the diameter ofthe axle, and bearing-blocks M are journaled upon the axle and fitwithin the ends of the tube. These blocks are secured to the tube so asto prevent relative angular movement of the two parts by means of anupstanding lug m, integral with the block M and entering a suitablelateral recess in the end of the tube. The lug 'm serves as a convenientsupport for some of the superframing of themachine, (not shown in thisapplication,) and hence is socketed. The block M is continued beyond thelug m and serves as a bearing for the journal-blocks 0, carried by thebrace-rod c.

The hounds O O of the pole O constitute bearing-blocks and are suitablyjournaled upon the tube H, and a brace-rod P, leading from one of theline-levers G, is rigidly secured to the tube H between these hounds byany suitable form of clip. By so disposing this brace-rod, it not onlystrengthens the forwardly-projecting frame, but adds to the rigidity ofthe main frame by serving as a stay for the pole O.

In operation the grain-platform tilts upon the axle B, the tube H beingrocked in the operation. The construction shown provides for adistribution of the pressure applied in driving the machine throughoutthe entire axle and permits the forwardly-projecting portion of themachine to be tilted Without disturbing and Without undue strain uponthat portion of the frame which is posterior to the driving-axle.

I claim as my invention 1. The combination with the drive-Wheels and anaxle carried thereby, of a sleeve mounted upon the axle and rotatableindependently of the drive-Wheels, a grain-frame rigidly fixed t0 thesleeve, a push-pole, and a journal-block for transmitting power from thepole to the axle, and being journaled upon the sleeve.

2. The combination with a pair of drivewheels and an axle carriedthereby, of a tube of great diameter and sleeved upon the axle,bearing-blocks set in the ends of the tube and free to turn upon theaxle, a vertically-adjustable grain-platform rigidly fixed to the tube,a driving pole or tongue journaled upon the tube, and brace-rods leadingfrom the pole or tongue to the bearing-blocks in the ends of the tubeand being journaled thereon.

In testimony whereof I aifix my signature in presence of two Witnesses.

ALBERT PARKER.
